Roommates & Shared Housing New Brunswick 5 min read · published March 09, 2026 Flag of New Brunswick

If your roommate suddenly abandons your shared unit in New Brunswick, you're not alone. This situation can feel overwhelming—especially if you’re worried about rent, utility bills, or potential impacts on your tenancy record. Understanding what to do next can help you protect your rights and minimize disruption.

Understanding Roommate Abandonment in New Brunswick

Roommate abandonment typically means that one person on the lease moves out and stops paying rent or sharing responsibilities, often without proper notice. In New Brunswick, whether you and your roommate are both on the official lease, or only one of you is, will affect your legal rights and next steps.

Types of Roommate Arrangements

  • Co-tenants: Both (or all) roommates have signed the lease with the landlord. Each is legally responsible for the full rent.
  • Subtenant/Unlisted Roommate: Only one person is on the lease, and the other is an occupant or a subtenant.

If your roommate leaves, you may become fully responsible for the rent. You may also be affected if damage or unpaid fees result from their departure. Tenant Rights and Landlord Rights in New Brunswick provides provincial basics to help clarify your obligations.

Immediate Steps if a Roommate Abandons the Unit

  • Contact your landlord to notify them of the situation
  • Document all communication with your roommate and landlord
  • Gather any evidence that shows your roommate has left (e.g. empty bedroom, returned keys)
  • Review your lease agreement for specific terms about joint responsibility

If you are concerned about covering rent alone, communicate honestly with your landlord—some may allow you to bring in a new roommate or may adjust the lease.

Ask for a written lease amendment adding the new occupant and confirm how rent will be shared. Request any changes in writing before the roommate moves in and keep a copy for your records.

Official Forms and Government Process in New Brunswick

In New Brunswick, residential tenancies are overseen by the Residential Tenancies Tribunal (RTT). Abandonment is dealt with under the Residential Tenancies Act1.

Relevant Official Forms

  • Notice to Terminate for Abandonment (Form 11): Download Form 11 (Notice of Abandonment)
    • When to use: If you are the tenant remaining but want to officially end the rental due to abandonment, this form can be used. For example, if rent cannot be paid alone and you wish to end tenancy early.
    • How to use: Fill out Form 11 and submit it to your landlord and the Residential Tenancies Tribunal. Keep a copy for your records.
  • Tenant’s Application (Form 5): Download Form 5 (Tenant’s Application)
    • When to use: To apply for a determination on rights and any monetary disputes stemming from a roommate leaving, such as a security deposit claim.

Your Rights and Responsibilities

Even if your roommate leaves, you are generally still responsible for paying the full rent and meeting the lease terms (unless otherwise stated). Your landlord may also be able to keep the security deposit to cover unpaid rent or damages. If you paid the deposit in full, you may have to seek compensation from your former roommate.

Document all payments and communications with your roommate—having a clear paper trail will help if disputes arise.

Security Deposits

If your lease ends due to abandonment, review Understanding Rental Deposits: What Tenants Need to Know to learn about recovering your portion of the security deposit. The Tribunal can decide how deposit funds should be distributed if there is a dispute.

Options for Remaining Tenants

  • Stay and pay full rent: You may continue the tenancy if you can pay.
  • Seek a replacement roommate: Always get landlord approval in writing before a new person moves in.
  • Terminate the tenancy: Use Form 11 and provide as much official notice as possible to minimize penalties.

What If There’s Damage or Rent Owed?

If unpaid rent or damages are caused by the departed roommate, you (and any remaining co-tenants) may be liable. The landlord can pursue all tenants named on the lease, not just the one who left. Legal action between you and your former roommate (for instance, in Small Claims Court) may be necessary if they owe you money.

Summary of Legal Position

New Brunswick’s Residential Tenancies Act holds all tenants named on a lease jointly responsible unless otherwise agreed in writing. The Tribunal can resolve certain disputes but cannot enforce private roommate arrangements not reflected in the lease.

To avoid disputes, ensure all joint responsibilities are documented in the lease or a formal addendum. Keep copies of amendments and note dates and signatures.
